Answer:

A = 28

B = 22

Step-by-step explanation:

All money will be recorded in pennies

Let A = the 45 Bulb

Let B = the 65 bulb

A + B = 50                                  (1)

45A + 65B = 2690                    (2)

Multiply (1) by   45 and subtract that from (2)

45A + 65B = 2690

45A + 45B = 2250        Subtract

          20B =   440

              B = 22

A + B = 50

A + 22 = 50

A = 50 - 22

B = 28

Check

45*28 + 22* 65  =

1260 +  1430 = 2690

Answer:

Number of seats in first row = 2

Number of seats in 2nd row = 4

Number of seats in 3rd row = 6

Step-by-step explanation:

Let's say number of seats in first row is x.

Now we are told that each row must have two more seats

than the one before it.

Thus, the remaining 2 rows have;

(x + 2) and (x + 4) seats respectively.

We are told that that the front row must have one quarter the total seats in the

back 2 rows combined.

Thus;

x = ¼((x + 2) + (x + 4))

Multiply both sides by 4 to give;

4x = x + 2 + x + 4

4x = 2x + 4

4x - 2x = 4

2x = 4

x = 4/2

x = 2

Thus;

Number of seats in first row = x = 2

Number of seats in 2nd row = (x + 2) = 2 + 2 = 4

Number of seats in 3rd row = (x + 4) = 2 + 4 = 6

Answer:

$38,640.00

Step-by-step explanation:

We know that Catrina earns $19.32 an hour. We also know she works 40 hours a week. So first, let's multiply 19.32 by 40 to see how much she makes a week.

19.32 × 40 = 772.80

Because of this, we now know that Catrina makes $772.80 a week. There are 52 weeks in a year. However, since she takes 2 weeks of vacation, we need to take off 2 weeks in the year. This leaves us with 50.

Finally, we multiply 772.80 and 50 to find her annual earnings:

772.80 × 50 = 38640

Therefore, her annual earnings will be $38,640.00.

Answer:

1 hour/ 32 miles

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given that:

Q1 = 14 − P1 − 0.5P2

Q2 = 19 − 0.5P1 − P2

Recall that:

Profit = Total revenue - Total cost

π₁ = P₁Q₁ MCQ₁

π₁ = P₁(14 - P₁ - 0.5P₂) - Q₁

π₁ = 14P₁- P₁² - 0.5 P₁P₂ - 14 + P₁ + 0.5P₂

π₁ = 15P₁ - P₁² - 0.5P₁P₂ + 0.5P₂ - 14

π₂ = P₂ (19 - 0.5P₁ - P₂) - 2(19 - 0.5P₁ - P₂)

π₂ = 19P₁ - 0.5P₁P₂ - P₂² - 38 + P₁ + 2P₂

π₂ = 21P₂ - P₂² - 0.5 P₁ P₂ + P₁ - 38

The profit functions are π₁  & π₂

The best-response function from firm 1  is;

π₁ = 15P₁ - P₁² - 0.5P₁P₂ + 0.5P₂ - 14

[tex]\mathbf{\dfrac{\partial \pi_1}{\partial P_1}= 15 - 2P_1 -0.5P_2 =0}[/tex]

[tex]\mathbf{P_1= \dfrac{15-0.5P_2}{2}}[/tex]

The best-response function from firm 2  is;

π₂ = 21P₂ - P₂² - 0.5 P₁ P₂ + P₁ - 38

[tex]\mathbf{\dfrac{\partial \pi_2}{\partial P_2}= 21 - 2P_2 -0.5P_1 =0}[/tex]

[tex]\mathbf{P_2= \dfrac{21-0.5P_1}{2}}[/tex]

Here we must find the profit for each one of the two stores.

Remember that profit is defined as the difference between the revenue and the cost.

For La Boulangerie we know that they sell Q1 thousand loaves. Each loaf costs $1. Each loaf is sold by P1

Then the profit is just:

P = Q1*(P1 - $1) = (14 − P1 − 0.5*P2)*(P1 - $1)

Which is already written only in terms of P1 and P2.

Similarly, for the other store we will get the profit:

P' = Q2*(P2 - $2) = (19 − 0.5P1 − P2)*(P2 - $2)

Now we must get their best response, which is given by deriving it with respect to the price and making it equal to zero:

For the first store we have:

dP/dP1 = $1 + 14 - 0.52*P2 - 2*P1 = 0

Now we solve it for P1:

P1 = ($1 + 14 - 0.52*P2)/2

Similarly, for the other store we have:

dP'/dP2 = 19 - 0.5*P1 - 2*P2 + $2 = 0

Solving it for P2 it gives:

P2 = (19 - 0.5*P1 + $2)/2

Answer:

The midpoint of the segment is (6,6).

Step-by-step explanation:

To solve this problem, we are going to use the midpoint formula, which is shown below:

( (x1+x2)/2, (y1+y2)/2 )

If we plug in the values that we are given in the question, we get:

( (8+4)/2, (9+3)/2)

We should add together the two numbers in the numerator of each fraction to begin the simplification process:

(12/2, 12/2)

Now, we can perform the division to find our final answer.

(6,6)

Therefore, the correct answer is (6,6).
